BANDI NG-MAGHINE ATTACHMENT.

Application filed November 11 .1922. Serial No. 600,341.

This invention relates to banding ma 1o chines used to cover paper boxes, and has for: its object the provision of a novel attache ment which may be set for any size box to cut the paper into pieces of the same length, the device operating as a great saver of pa er. 1

, n important and more specific object is the provision ofadevice of thischaracter which replaces the usual swirrging knife.

structure and which includes a slidalbly mounted knife operated by a novel cam it 7 mechanism. e 1

Another object isgthe provision of device of this characterrwhiohris provided with a, kicker roller whichtwilloperate to cause the? cut edge of the remaining paper to be projected so that it may be grasped bythe operator.

An additional object is the provision of a device of this character which will be simple 3 and inexpensive in manufacture, easy to install, economical and positive in operation,

durable in service and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which: 7

Figure l is a side elevation of a banding machine showing my device applied thereto,

Figure 2 is a front elevation,

Figure 3 is a plan view,

Figure 4 is a vertical section on the line 44 of Figure 2,

Fi re 5 is a cross section on the line 55 of F igure 2,

Fi ure 6 is a fragmentary elevation showing t e pawl and ratchet mechanism.

Figure 7 is a fragmentary view showing the trip mechanism,

Figure 8 is a detail view of the cam.

Referring more particularly to the drawings the letter A designates, broadly, a banding machine of the type commonly provided with a swingably mounted knife operated by a control lever and treadle and having a certain spring mechanism associated therecarrying, out my invention the ordinary swinging knife structure is eliminated and replaced by the ignechanisn v to be descnibed; Machinesofthistype include an upstandingframeB carrying guide rollers. Gland- D for the paper E which unwraps from aroll Rand which passes over a roller Gr dipping into a tank or pan H of adhesive.

The numeral 10 designates a pair of;supportingbrackets suitab y mounted upon, the

machine and. formed. with dovetailed 1 m. ways..11 which constitute uides fonb ocks 3 which extends,

12 which carry a knife transversely of the machine. Suitably mounted below this ,knife is a. stationary knife 14 co-aotirig therewith..- Qrdinar ily. the knife 13 is urged toward theknife 14 by a pair of coil springs 15 connected with the supporting bracket and with theblocks 12 as shown; Projecting outwardlypifro-m these blocks 12 are studs, 13- upon which are journaledrollers 17 located outwardly of the supportsld. a p pp a Journaled through thesupports :1 above the knife 13 is a, shaft 18 carrying rolers, 19 which co-act wit-h the roller D for engag ing and feeding the paper. At one end this shaft 18 carries a ratchet 20 which is engaged by a spring pressed pawl 21 on the adjacent block 12 for the purpose of partially rotating the shaft and rollers at every movement of the knife 13.

Journaled through the supports 10 below the stationary knife 14 is a shaft 22 which has its ends carrying cams 23 which engage the rollers 17 for the purpose of raising the knife 13 at fixed intervals. At one end the shaft 22 carries a gear 24 with which meshes an intermediate gear 25 journaled on a stud 26 peculiarly mounted as will be described the gear 25 in turn, meshing with a gear 27 on a hub 28 mounted upon a spindle 29 which carries the support for the box to be covered, illustrated at 30. The stud 26 is carried by a slotted lever 32 adjustably mounted on the frame so that the gear can be raised and lowered.

The numeral 33 designates an angular lever pivoted at 33 on the arm 32 and having an end 33 bearing against the periphery of a disk 34 adjustably held on the spindle 29 by a, set screw 37. The lever is en aged by a sjiriiigvvhilli urges in; are 'I- tion, and its swinging moverfisnravvay' rolh the disk is limited by a stop pin 36. Carried by the lever 33 a gage $8. The disk is formed in its periphery with a notch 34 designed to receive the end 33 of lever.

In the operation it will be seen that when the spindle 29 is rotated the act-bf final in the box and its support 30, thegear 27 W1 I operate to drive the gear 2'5 and gear as pon, the cams 3 'fng the ro'He'fs 1" will 'caiis'e the ihovab e nife to "have an up wmr ins-vermin agaihst th 0f the springs.
